ABSTRACT:
A contact blade assembly for a circuit breaker comprises a blade carrier, an elongated blade, and a toggle spring. The blade carrier includes a blade pivot and a first spring pivot. The elongated blade has an electrical contact mounted thereto and includes a second spring pivot. The blade is rotatably mounted to the blade pivot of the blade carrier for rotation between a closed position and an open position. The toggle spring is connected to the first spring pivot at one end and to the second spring pivot at the other end. The first spring pivot, the second spring pivot, and the blade pivot are arranged such that a toggle condition associated with the rotation of the blade relative to the blade carrier corresponds to the blade pivot being located in line and between the first and second spring pivots. The toggle spring biases the blade away from the toggle condition in a first direction while the blade is disposed in the closed position. The toggle spring biases the blade away from the toggle condition in a second direction opposite the first direction while the blade is disposed in the open position.
